General Background:
The JS tanks were named after Joseph Stalin. The JS-2 had a 122mm D-25T main gun and 6
road wheels to improve soft ground track performance. In 1944 new specifications included new armor tempering, a 60-degree glacis replaced the 30-degree and the driver’s front hatch was removed. Also a relocated wider porthole, improved mantlet, increased lower hull side armor and a new periscope sight. The commander’s cupola moved to the left and a 12.7mm anti-aircraft machine gun attached. In 1944 2,250 JS-2’s were produced and no further improvements were made until 1954.
The Tank:
In late April 1945 Soviet forces began their assault on Berlin capturing the city on May 2, 1945. As part of the operations JS-2 Heavy tanks were called in whenever Soviet forces needed a German tank or building destroyed. The use of HE (High Explosive) incendiary ammunition made the JS-2 very deadly. Regular Guard units had 3 regiments of 65 JS-2s per regiment but the Independent Guard units had far fewer. The 88th Independent Guards Heavy Tank Brigade was part of the 1st Belorussian Front.
